I agree, but I suspect that we don't agree on the specific quirks to be left 
behind.

The unary & is on the top of my list. &x should never be overloaded, IMHO. 
Yes, we do have addressof. I'd still have gone with addr(_1) instead.

The other thorny issue is that lambda expressions aren't Assignable, because 
their operator= creates a new lambda exression instead. This might well be 
unfixable.

I've always thought that the plan was for Lambda and Phoenix to merge one 
day.

Apart from that, I'm not a Lambda user, so I don't have an opinion. :-)
